Shipping Pick List

The Shipping Pick List is a list of all of the Inventory Objects that have been ordered, and are in shipments that have not yet been marked as "shipped". Once a shipment has been marked as "shipped", its corresponding Inventory Objects will be removed from the list.

This is a great idea. I've submitted this to the Development Schedule for consideration to be added in an upcoming software update. This would require adding a new field to the database, and any changes that require changes to the database structure usually require a little extra testing before being approved for release. The progress of this item can be tracked within your store's Administration Area at: [Support > Development Schedule].
